The electron transport system is a series of _________ reactions.
A)composition-decomposition
B)dehydration synthesis-hydrolysis
C)oxidation-reduction
D)reversible

Question

Quizplus · Accepted Answer

The electron transport system involves the transfer of electrons from high-energy molecules to lower-energy molecules, which is a process of oxidation-reduction reactions. This is the main mechanism by which cells extract energy from food, so it is not reversible like some reactions. Choice A is incorrect because composition-decomposition reactions involve the breaking and forming of covalent bonds, which is not a feature of the electron transport system. Choice B is also incorrect because dehydration synthesis and hydrolysis reactions involve the formation or breaking of chemical bonds through the addition or removal of water molecules, which is not a feature of the electron transport system.
